Professional Applications & Engineering Value
This zinc-flake-coated steel wedge lock washer delivers critical vibration resistance where conventional fasteners fail. The dual serration pattern on both top and bottom surfaces creates multiple biting points that resist rotational forces in heavy machinery, construction equipment, and transportation systems. Unlike standard washers that can loosen under cyclic loading, this wedge lock design maintains constant tension while the Rockwell C46 hardness prevents deformation under extreme pressure. The zinc-flake coating provides superior corrosion resistance compared to traditional plating methods, making it ideal for outdoor infrastructure, marine applications, and chemical processing facilities where environmental exposure compromises fastener integrity.
Specification Summary & Compliance
Manufactured to precise dimensional tolerances with 1.95" inner diameter and 2.95" outer diameter, this wedge lock washer maintains consistent 0.270-0.290" thickness for uniform load distribution. The dual serration configuration ensures maximum locking performance for both inch (1 7/8") and metric (M45) screw systems. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, this washer meets international environmental and safety standards for industrial components.
